SpaceX will lose up to 40 satellites it just launched due to a solar storm
CNN
Up to 40 of SpaceX's Starlink satellites are expected to fall out of orbit thanks to some inopportune timing: The company launched the satellites directly into a solar storm.
A batch of 49 Starlink internet satellites were on SpaceX's latest launch on February 3, and now the company is expecting to lose most of them because they hit a space weather event known as a geomagnetic storm. This event occurs when streams of charged particles, or solar winds, emitted from the sun interact with Earth's magnetic field. The energized particles can heat up the upper atmosphere, causing it to thicken. (Yes, there is still atmosphere in areas of outer space closest to home. The Earth's atmosphere fades out over thousands of miles.)
In this case, the storm impacted the area of orbit where SpaceX's newest Starlink satellites were deployed, and it made the atmosphere dense enough that the satellites weren't able to maneuver their way up to their intended orbit.
